Toews Environmental Water Quality Monitoring Program

On behalf of the Rural Municipality of Yellowhead, Toews Environmental Ltd. led studies on Shoal Lake, Manitoba, to inform development of a lake water level management plan and possible future initiatives to improve water quality in the lake. The water quality study comprised collection of water samples and in situ measurements from four locations on the lake in March, June, July, August and October 2018. Laboratory analyses focused on nutrients and related parameters including metals and phytoplankton taxonomy. Measurements from near the lake bottom at the deepest site will allow assessment of internal phosphorus loading.

Informations sur la collecte de données

Surface grab samples were collected directly into the laboratory-supplied bottles from approximately 30 cm below the water surface in summer and with a Van Dorn sampler from approximately 30 cm below the ice in March. Bottom samples were collected with a Van Dorn sampler from approximately 30 cm above the lake bottom. As applicable, samples were preserved and/or filtered with a syringe-mounted 0.45 µm membrane filter on site. Vertical profiles of dissolved oxygen, specific conductance and temperature were measured with a YSI 556 multimeter.

Traitement de la collecte des données

No processing of the data was conducted beyond standard QA/QC conducted by the analytical laboratory, reported to the client.
